How Many IT Companies Are in the UK in 2026?
April 2026 · Data sourced from Companies House
The UK's technology sector is enormous. Across three sub-categories — IT consulting, software development, and IT services — there are approximately 275,000 active IT companies registered at Companies House as of March 2026.
Breakdown by Sub-sector
IT Companies by Region
London dominates the UK tech landscape, with over 54,000 IT consulting companies alone. The South East is a strong second, driven by the Thames Valley and M4 corridor tech clusters.
International Ownership
The IT sector has the highest rate of international ownership of any UK industry. PSC data reveals significant numbers of Indian, Chinese, Pakistani, and American nationals controlling UK tech companies — particularly in London and the South East. This reflects the UK's role as a global technology hub and the prevalence of skilled worker visa holders setting up consultancies.
